Data for: Mitigation of the error field and eddy currents for start-up of spherical tokamak using compensation and reverse coils

we minimized eddy current density on central cylinder and vertical component of magnetic field in side the vacuum chamber using a pair of compensation coil.本研究采用一对补偿线圈，将中心圆筒的涡流密度与真空室内部的磁场垂直分量降至最低。
